Thanks for quick testing.

Then could you load alsa-info.sh output from the patched kernel after suspend/resume? Run the script with --no-upload, and use Bugzilla attachment.

Thank you. Sorry but I have no idea how to run this script. where is located? so sorry, I'm not that expert :D

Also, for verifying whether it's a driver PM problem, try the following:

- Before and after suspend/resume, try to play without PA, PW or JACK but via ALSA native API, e.g. % aplay -Dplughw:XXX foo.wav where XXX is the card number like 0, 1, 2, corresponding to the device index appearing in /proc/asound/cards.

I suppose this also results in the mono output?

Yes indeed. It does sound as mono after waking up from sleep

- Check whether the problem persists with suspend-to-RAM and suspend-to-disk (hibernate). I assume you're dealing with the former, right?

Hibernate it doesn't work on my PC (maybe because I don't have a swap partition?).

- Last but not least, check whether re-loading the driver fixes the problem without re-plugging. You might need to go out of desktop session once, unload snd-usb-audio module and re-load snd-usb-audio module on Linux console.

Again, so sorry but I don't know how to stop and re-load this module. -- You are receiving this mail because: You are on the CC list for the bug.
